Anhydrous Ammonia is a liquid when compressed and liquefied under high pressure and low temperature. Liquid Ammonia vaporizes as soon as it gains adequate temperature and/or exposure to the atmosphere.
It has a strong and pungent odour; so much so that, even at a miniscule level of exposure its presence can be detected even though it is a colourless gas by its characteristic smell. This property of Ammonia is its biggest safety feature.
The chemical formula of Ammonia is NH 3 with UN No. 1005 and CAS registry 7664-41-7. Ammonia is a versatile chemical and therefore has a wide range of applications across Industries. As a basic chemical several Industries like Rubber, Pharmaceuticals, Chemicals, and Refrigeration among others use Anhydrous Ammonia in its liquid, and/or gaseous state.
At temperatures over 450ºC, Ammonia decomposes to liberate Hydrogen and Nitrogen gases though it may decompose at lower temperatures in the presence of appropriate catalysts.
Liquefied Ammonia is supplied in steel containers of varying capacity ranging from 40 to 60 kg Cylinders, 400 kg Tonners, 6 to 15 MT Tankers and ISO Tanks. All of these packaging units with capability to withstand higher pressures are compliant with necessary statutory requirements of the Petroleum and Explosives Safety Organization and the International Maritime Organization as applicable.
In an open and well ventilated area, Ammonia is generally not a fire hazard while in a closed and confined area Ammonia may be a fire hazard, especially if oil and other combustible materials are present.
Galvanized surfaces, aluminum alloys, brass, bronze, copper, gold and silver gets corroded on exposure to Ammonia Gas.
